Shearwater Group PLC (AIM:SWG) shares climbed 11%, to 47.2p, after announcing that its subsidiary Brookcourt Solutions has secured a £7.3 million contract extension with a major UK mobile network operator.
The deal covers three years and expands existing work on data security infrastructure.
The cyber security firm said £6.1 million of the contract value relates to Thales Imperva Data Security Fabric licences, with £1.2 million attributed to Brookcourt’s managed services.
Shearwater expects £3.5 million of revenue to be recognised in FY26.
"This contract extension represents a strong validation of the value we deliver to major critical infrastructure organisations," CEO Phil Higgins said. He added that the work strengthens long-standing ties with the customer at a time of increasing cybersecurity risk.
